I can zoom in but want to limit the zoom?

Currently there is no limit. In the "Inspect" mode, the length of the LookDirection is reduced while keeping the CameraPosition+LookDirection point fixed.
I will add this as a new feature in the issue tracker!

Hey Objo,
Please if you add that feature to limite the camera zoom tell me how to implement it.

If the property is inspectable, a mouse wheel event, or CTRL+, CTRL- event, could be used to limit a requested change...
